Low density parity check decoder for irregular LDPC codes Patent uri icon

abstract

  • A method and system for decoding low density parity check (LDPC) codes. An LDPC decoder includes an R select unit, a Q message first-in first-out (FIFO) memory, and a cyclic shifter. The R select unit provides an R message by selecting from a plurality of possible R message values. The Q message memory stores a Q message until an R message is generated by a CNU, the Q message and the R message are combined to provide a P message. The cyclic shifter shifts the P message.
